Energy saving device of building outer window

Abstract

The invention provides an energy saving device of a building outer window. The energy saving device comprises a window auxiliary frame, a window frame, a heat insulating filling material, an outer wall heat insulating material, an outdoor decorative surface and a waterproof layer. The window auxiliary frame is fixedly connected with a wall body through an upper wall connecting part, the window frame is fixedly connected with the window auxiliary frame, the portion between the window auxiliary frame and the wall body is filled with the heat insulating filling material, the outer wall heat insulating material is fixedly connected to the outer side of the wall body, and the outdoor decorative surface is located on the outer side of the outer wall heat insulating material and fixedly connectedwith the window frame. The energy saving device further comprises a heat insulating waterproof layer, the heat insulating waterproof layer is fixedly arranged between the window frame, the window auxiliary frame and the heat insulating filling material, one end of the heat insulating waterproof layer is fixedly connected with the outer wall heat insulating material, the other end of the heat insulating waterproof layer is clamped between the window auxiliary frame and the window frame, and the heat insulating waterproof layer is formed by integrating an aerogel heat insulating strip and a waterproof layer covering the outer side of the aerogel heat insulating strip. The energy saving device of the building outer window is simple in structure, continuous heat insulating of the joint of thewindow frame and the wall body can be achieved, the energy saving effect of the whole window is improved, and dew formation is avoided.

Description

technical field [0001] The invention relates to an energy-saving structure, in particular to an energy-saving structure at the joint between a window frame and a wall. Background technique [0002] The connection between the external window and the wall of the building is the weak link of the thermal performance of the whole window. If it is not handled properly, it will cause a series of thermal problems such as increased building energy consumption, reduced indoor thermal comfort, and condensation causing interior decoration damage and mold. . At present, in the relevant codes and standards of building exterior windows in my country, there are detailed design standards and performance requirements for the air tightness and thermal insulation performance of the entire window, but there is no air tightness and thermal insulation performance for the connection between the window and the wall. Clear design standards and performance requirements, and the lack of reliable inspec...

Problems solved by technology

The two types of attached frames have their own advantages and disadvantages. Metal attached frames have better strength and aging resistance, but poor thermal insulation performance; non-metallic attached frames have better thermal insulation performance, but poorer strength and aging resistance, and the price is higher

[0005] In some cases, in order to reduce the thermal and cold bridge effects caused by the attached frame, traditional insulation materials such as thermal insulation cotton and polyurethane foam will be filled outside the attached frame. It is very difficult to process into a narrow and irregular shape, the construction process is complicated, and there are great difficulties in installation and fixing, and the insulation cotton and other materials are easy to absorb water and moisture, and the actual effect is far from the expected; then use polyurethane foam, etc. Take organic materials as an example. During the filling process of such materials, due to the limitation of on-site operation conditions, the filling of the cavity is prone to dissatisfaction, resulting in thermal and cold bridges, which make the material and the base material peel off and fall off. The anti-aging performance and fire protection performance of the material are very poor, so that the durability of the whole window is insufficient, and there are potential safety hazards
